] 2 Claims.

The present invention relates to ventilated covering of cavities.

Various cavities, such as gutters on the edges of roots, catch basins, and the like usually are kept open and thereby permit of such things as leaves and the like to enter the cavity and cause plugging up of passages therein. Solid covers have been used in such instances as sewer hole covers but these are not ventilated for good reasons.

The present invention aims to provide a cover for cavities, which do not need a solid cover, with a ventilation means and with means whereby obstructive things are easily removed from the top of covers and to prevent such things from entering a cavity.

Objects of the present invention are: To provide a simple, cheap, efficient, economical in structure, and easily removed and applied cover for cavities. To provide an easily applied and easily removed cavity cover with a ventilated cover sheet and with waves so that material falling thereon can lay on the crests of the waves and be easily removed with a broom or the like or by wind entering below the crests and below the material and blowing the material off of and away from the cover. To provide ventilating holes through a cover to ventilate a cavity and to permit Wind to get to the underside of the cover and aid in blowing material off of the cover. To provide a cover with a binder around the edges thereof to stiffen the ventilating sheet to strengthen the cover as a whole and to act as a means for resting the cover on a cavity. To provide a leg or foot means which may contact on a wall of a cavity to keep the cover in a definite relation with the opening of a cavity. To provide an anchoring means on a cover to hold the same in a definite relation to a cavity when desired.

Other objects will appear in the description of the cover means shown and described below, or will become obvious or apparent or will suggest themselves upon inspection of the accompanying drawing and this specification.

The principle of the present invention is illustrated in the accompanying drawing which shows a cover as applied to a gutter and wherein:

Fig. 1 is a general plan view of a cavity cover, embodying the present invention, and showing the cover as applied to a gutter.

Fig. 2 is a longitudinal section taken on line 22 of Fig. 1 and shows the longitudinal relation of the cover to a portion of the gutter.

Fig. 3 is a transverse section taken on line 3-3 of Fig. 2 and shows a transverse relation between the cover and a gutter.

Similar reference characters refer to similar parts throughout the views.

The device shown in the accompanying drawing, forming part of this specification, comprises, principally, the sheet A and the binder B.

The sheet A, in the instance shown, is rectangular and may be made of any suitable material, preferably metal and, when such metal is subject to corrosion, a coat of paint or of plating or equivalent may be applied to cover every part of the cover to prevent such corrosion. Such coat is, preferably, applied after the cover is finished so that all parts thereof are covered including the edges on cut off of material or bruises made during construction of the cover when the raw material had been coated.

The sheet A, represented in the drawing by heavy lines, may be made in various manners. A sheet of solid material may have holes punched therethrough and have below described waves impressed in the sheet. The sheet A may also be made, and preferably is made, of woven wire or cloth, preferably of coarse mesh, as illustrated in the drawing, and the waves formed therein.

The idea is to provide a ventilated and ventilating cover and preventing material from getting through the cover and into a cavity by having holes therethrough and to provide waves on the cover so that material does not lay fiat on the cover but lays on the crests of the waves to let wind get in under the sheet.

The binder parts Ill or margin or framing is also a supporting means for the sheet A and, in the instance shown, is of round material, preferably metal, is rectangular in outline to correspond to the rectangular sheet A, and extends around on the edges of the sheet A and acts as a supporting means for the cover as awhole on a cavity.

The edges of the sheet A are bent over the binder parts It! to keep the sheet A in relation to the binder parts.

All of the waves l l shown extend above the binder so that any material falling thereon must lie above the binder and above a cavity so that wind and broom and the like can easily remove material falling thereon.

The waves may be spaced regular or irregular and all may have the same form or be different in form as the drawing shows.

It is preferred that a staggered relation exists between the waves which may be attained by the two longitudinal rows of waves shown or by staggering the waves in any other manner. This staggered relation of waves permits winds from difierent directions to get under the material on the waves.

The leg or foot member I2 is attached to and depends from the cover to support the same but is unnecessary as a leg or foot when the binder finds suflicient support on a cavity. However,

this leg'or foot may be used as an anchoring means against lateralmovement of the cover by extending through an opening in the gutter C, which is here representative of a cavity, or by being driven through a wall of the same. Many gutters have a recessed part I 3 into'which one' side of the cover is extended and therebyprevents straight upward movement of the cover.

The device shown and described is easy and convenient and economical of structure and of application to and removal from a cavity, eliminates collection of material in a cavity to which the. cover is applied, provides ventilation of a cavity to which the cover isv applied, and permits of easy and convenient removal of material from the cover when some does collectithereon.

2. A cover for a roof gutter comprising a screen and a binder on the margin of the screen'for support thereof relative to the gutter; said screen having hollow, irregularly formed and irregularly spaced waves formed therein above the binder to permit wind coming from different directions to reachrthe hollow of the waves for ventilation of the gutter and removal ofmaterial from the .top of the waves.
